With temperatures warming up this week, ice conditions at many Iowa lakes are changing quickly. DNR conservation officers urge caution as conditions for ice- related activities, such as fishing and OHV riding, deteriorate.

“Ice conditions have been changing by the day, and even by the hour in some places,” said Craig Cutts, Iowa DNR Law Enforcement Bureau Chief.

Lack of snow cover, which typically slows winter ice melt even on slightly warmer days, means sunshine and warm temps will cause the ice to crack and contract, making ice unpredictable and potentially dangerous.

According to Cutts, when there is no snow cover, areas closest to the bank of the lake will become dangerous first. “This is where you can go through quickly, so be sure and check ice thickness every step of the way.”

Use caution if heading out and keep plenty of distance from open water. The standard safety practices of checking ice thickness frequently, and including a life jacket, throwable floatation and 50 feet of rope with your fishing equipment is encouraged.

“We emphasize that ice thickness varies on each body of water. It’s a good reminder that no ice is 100 percent safe – and to trust your instincts – if it doesn’t look right, stay off,” Cutts said.
